Abstract: In our proposed system, the vehicular sensor network (VSN) is formulated based on the cognitive radio with the aid of optimal link state routing (OLSR) protocol. Here the cognitive radio related vehicular sensor networks are anticipated for the data communication. The optimal link state routing protocol is modified by utilising the hybrid group search and genetic algorithm (HGSO-GA) algorithm. The OLSR protocol is used to pick the adjacent nodes which disseminate the power package to diminish the quantity of control transparency in the network. The data packages are conveyed from source to destination with the help of multi point relay (MPR) vehicles, which is the subset of the chosen neighbour vehicles by each source to access all the two-hop neighbours act as forwarders. OLSR routing protocol to efficiently manage spectrum allocation that helps reduce the routing delay. The proposed technique is implemented in the working platform of NS2.
